Reaktionsschritte

--A solution of α-bromotoluic acid (1.08 g) in dry benzene (10 ml) was stirred for 2 hours with thionyl chloride (0.73 ml) and dry DMF (five drops). The reaction mixture was evaporated to dryness, taken up in toluene and evaporated again. The crude product was crystallized from n-hexane (10 ml, charcoal) thereby obtaining pure α-bromotoluic acid chloride (0.95 g) as white flakes.
